{"cve":"CVE-2023-45822","nvd":{"published":"2023-10-19T21:15:08.930","modified":"2026-06-17T06:29:35.747","status":"Modified","description":"Artifact Hub is a web-based application that enables finding, installing, and publishing packages and configurations for CNCF projects. During a security audit of Artifact Hub's code base a security researcher identified a bug in which a default unsafe rego built-in was allowed to be used when defining authorization policies. Artifact Hub includes a fine-grained authorization mechanism that allows organizations to define what actions can be performed by their members. It is based on customizable authorization policies that are enforced by the `Open Policy Agent`. Policies are written using `rego` and their data files are expected to be json documents. By default, `rego` allows policies to make HTTP requests, which can be abused to send requests to internal resources and forward the responses to an external entity. In the context of Artifact Hub, this capability should have been disabled. This issue has been resolved in version `1.16.0`. Users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-918"],"references":["https://artifacthub.io/packages/helm/artifact-hub/artifact-hub?modal=changelog&version=1.16.0","https://github.com/artifacthub/hub/security/advisories/GHSA-9pc8-m4vp-ggvf","https://www.openpolicyagent.org/","https://www.openpolicyagent.org/docs/latest/#rego","https://artifacthub.io/packages/helm/artifact-hub/artifact-hub?modal=changelog&version=1.16.0"],"products":["artifacthub:hub"],"source":"nvd","synced_at":"2026-10-19T21:40:11.519948003+00:00"},"epss":{"cve":"CVE-2023-45822","score":0.0064,"percentile":0.50669,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9pc8-m4vp-ggvf","url":"https://osv.dev/vulnerability/GHSA-9pc8-m4vp-ggvf","summary":"Artifact Hub allows unsafe rego built-in","modified":"2024-08-21T14:56:49.098837Z","packages":[{"ecosystem":"Go","name":"github.com/artifacthub/hub","purl":"pkg:golang/github.com/artifacthub/hub","ranges":["<1.16.0"],"fixed":["1.16.0"]}]},{"id":"GO-2023-2134","url":"https://osv.dev/vulnerability/GO-2023-2134","summary":"Artifact Hub allows unsafe rego built-in in github.com/artifacthub/hub","modified":"2026-03-03T04:54:18.923222Z","packages":[{"ecosystem":"Go","name":"github.com/artifacthub/hub","purl":"pkg:golang/github.com/artifacthub/hub","ranges":["<1.16.0"],"fixed":["1.16.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
